Abstract

The invention relates to a connecting element, in particular a thermal material locking projection, which is introduced into at least one component, in particular a plate-shaped cavity component having a cavity, under the action of pressure and rotation, comprising a base part which comprises a thermoplastic synthetic material, has a longitudinal axis and is designed to rotate about the longitudinal axis, has an upper side with a tool placement region and a lower side facing away from the upper side, and has an expansion section made of a thermally activatable expandable material on a circumferential surface of the base part extending between the upper side and the lower side.

Description

Connecting element and method for introducing a connecting element
Technical Field
The invention relates to a connecting element, in particular a thermobonded projection, for introduction under pressure and rotation into at least one component, in particular into a hollow-chamber component having a hollow chamber, in particular a plate-shaped hollow-chamber component, comprising a base part comprising a thermoplastic synthetic material, wherein the connecting element has a longitudinal axis and is designed to rotate about the longitudinal axis, wherein the connecting element has an upper side with a tool placement region and a lower side facing away from the upper side. The invention also relates to a method for introducing such a connecting element into a particularly plate-shaped cavity component having a cavity.
Background
Similar connecting elements are already known from the prior art. DE 102014204449 a1, for example, shows such a connecting element. Furthermore, DE 102015208671 a1 likewise shows a connecting element with the features of the preamble of claim 1.
Such connecting elements are used in particular in the aircraft industry in order to introduce these connecting elements into one or more cavity members. When introduced into a plurality of cavity members simultaneously, a connection of the cavity members to each other may be provided. When introduced into a single cavity member, the functional elements provided on the connecting element can be fastened to the cavity member. Thus, for example, connecting elements with a central channel are known, which can be used for cables or the like to pass through when the connecting element is introduced into the cavity component.
The cavity element here generally comprises a base layer, a cover layer and a honeycomb structure arranged between the base layer and the cover layer. The base layer and the cover layer are advantageously made of glass fibre mats impregnated in epoxy resin, the honeycomb structure being made of aramid fibres or paper impregnated in phenolic resin.
When introducing connecting elements known from the prior art, it has been shown that: their fastening in the cavity member is in some cases insufficient, so that the connecting element can be detached from the cavity member again. However, it is precisely in the aircraft industry that a permanent, secure fastening of the connecting element is absolutely necessary. On the other hand, due to the often large number of connections in the aircraft industry, cost-effective connection elements are required.
Disclosure of Invention
The invention is therefore based on the following object: a connecting element for introduction into a cavity member is provided, which can be permanently fastened securely in the cavity member and which should be inexpensive to produce.
This object is achieved by a connecting element having the features of claim 1. The connecting elements of this type are distinguished by: the connecting element has an expansion section made of a heat-activatable expandable material on a circumferential surface of the base element extending between the upper side and the lower side.
The connecting element is advantageously designed to be substantially rotationally symmetrical and has a tool seat for transmitting torque in the region of the base part on the upper side. What can be achieved thereby is: an axial force is applied in the direction of the longitudinal axis to the connecting element for introduction into the cavity member and simultaneously drives it in rotation about the longitudinal axis.
When introduced into the cavity member, the heat-activatable expandable material of the expansion segment can extend into the cavity of the honeycomb structure of the cavity member due to the heat generated by friction between the connecting element and the cavity member, so that an additional undercut can be created below the cover layer of the cavity member, by means of which undercut the connecting element can be securely fastened in the cavity member.
A first advantageous development of the connecting element provides for: a groove is provided in the base element, in which groove the expansion section is arranged. It has proven particularly advantageous here that: the groove is circumferential. Here, one can consider: the grooves are rectangular grooves or have a semicircular cross section. It goes without saying that other groove cross sections are conceivable which can be produced simply in terms of production technology. It has also proved advantageous: in the dispensing state, the surface of the expansion section is flush with the circumferential surface of the base piece. Advantageously, the grooves are arranged in the upper third or quarter in the direction of the longitudinal axis, i.e. in the upper third or quarter towards the upper side, so that undercuts made of expandable material can be introduced into the region of the cover layer of the cavity element.
According to a particularly preferred embodiment of the connecting element: the heat-activatable material is a thermoplastic which comprises, in particular, a heat-activatable blowing agent. Here, it is conceivable that: the blowing agent sublimes upon heating.
Advantageously, the heat activatable expandable material is configured to expand under the action of heat. Thus, the heat-activatable expandable material may expand into the cavity of the cavity member based on frictional heat generated upon introduction into the cavity member.
It is furthermore advantageous: a metal sleeve is provided which is arranged in the base part and is concentric to the longitudinal axis. Advantageously, the sleeve has a cylindrical opening or bore, so that in the event of a connection element being introduced into the component or cavity component, the cable can pass through the opening or bore. Advantageously, the connecting element has a length in the direction of the longitudinal axis, which length is selected such that the connecting element introduced into the cavity member penetrates the cavity member completely. Since partial melting of the connecting element occurs when it is introduced into the cavity member, it can be provided that: the original length of the connecting element is about 30% greater than the thickness of the cavity member.
The metal sleeve is advantageously made of aluminum or stainless steel.
A further particularly advantageous development of the connecting element is distinguished by the fact that: the metal sleeve has a plasma-treated surface and is at least partially injection-encapsulated by the thermoplastic synthetic material of the base piece. It is particularly preferred here that the surface of the sleeve is plasma nitrided. The adhesion of the thermoplastic composite material to the metal sleeve can thereby be improved. Alternatively or additionally, it is conceivable that: the sleeve has a non-cylindrical region which protects the sleeve in the thermoplastic synthetic material against torsion, for example a square or hexagonal head. However, knurling, ribbing, and/or grooving of the surface of the sleeve is also contemplated. However, the introduction of ribs, grooves or knurls and the use of square or hexagonal heads leads to overall larger connecting elements due to the necessary wall thickness of the sleeve and the size of the square or hexagonal head. Plasma treatment of the surface has thus proved to be particularly advantageous, since metal sleeves having a relatively thin wall thickness can be used.
The metal sleeve is advantageously closed by the base part in the region of the underside, or the base part has an opening in the region of the underside, which opening is arranged concentrically to the longitudinal axis of the connecting element. It has proven to be advantageous if the metal sleeve is closed by the base part in the region of the underside: the lower side of the base part is pierced by a tool, in particular by a tool that drives the connecting element, when it is introduced into the cavity component, thus creating an opening through the connecting element from the upper side to the lower side along the longitudinal axis. Accordingly, the cable may be passed through the metal sleeve of the connection element introduced into the cavity member.
It is furthermore advantageous: the thermoplastic synthetic material of the basic element is polyamide or polypropylene. Among the possibilities are: the basic element is composed entirely of thermoplastic synthetic material. However, it is also conceivable for the base part to consist of a thermoplastic synthetic material and a corresponding proportion of glass fibers. Advantageously, the thermoplastic synthetic material is polyamide 6, polyamide 66 or polyamide 666.
According to a further particularly advantageous development of the connecting element, it is provided that: the connecting element has a radius in the range of 1 mm to 2 mm at the transition between the lower side and the circumferential surface. Such radii have proven to be particularly advantageous for process engineering reasons.
The object mentioned at the outset is also achieved by a method having the features of claim 11 for introducing a connecting element according to one of claims 1 to 10 into a particularly plate-shaped cavity component having a cavity. The method is characterized in that: the connecting element is driven in rotation about its longitudinal axis and an axial force is applied by means of a tool in the direction of the cavity member along the longitudinal axis of the connecting element, so that the heat-activatable expandable material expands in particular into the cavity of the cavity member due to the heat generated by friction between the connecting element and the cavity member. Pre-punching of the cavity member can be avoided here.
A first advantageous development of the method provides for: the connecting element is introduced into the cavity component in such a way that it penetrates the cavity component completely after introduction in the direction of the longitudinal axis of the connecting element.
It has proven particularly preferred here that: the connecting element has a metal sleeve which is arranged in the base part and is concentric to the longitudinal axis, wherein the cable is guided through said sleeve after being introduced. Thus, the cable may pass through the cavity member. If a connecting element is used in which the metal sleeve is closed by the base part in the lower region, it is advantageously provided that: when the connecting element is introduced, the base part is pierced by a tool in the region of the lower side of the connecting element, so that an opening is produced through the connecting element along the longitudinal axis from the upper side to the lower side.
It is furthermore advantageous: the tool applies an axial force to the connection in the range of about 800 newtons to about 1200 newtons, preferably about 1000 newtons.
The coupling is advantageously driven by the tool at a rotational speed in the range of about 4000 rpm to about 6000 rpm, preferably about 5000 rpm.

Detailed Description
Fig. 1 to 4 show cross-sectional views of various embodiments of a connecting element 10 according to the invention along the line a-a according to fig. 5. Corresponding elements are denoted by corresponding reference numerals herein.
Fig. 6 shows schematically a connecting element 10, also referred to as a thermal material locking projection, which is designed to be introduced under pressure and rotation into a plate-shaped cavity component 14 having a cavity 12.
The connecting element 10 is designed substantially rotationally symmetrical and has a base part 16 which comprises a thermoplastic synthetic material. The connecting element 10 also has a longitudinal axis 18 and is designed to rotate about this longitudinal axis 18. The connecting element 10 has an upper side 20 with a tool seat 22 for transmitting torque and an underside 24 facing away from the upper side 20.
Such connecting elements 10 are used in particular in the aircraft industry in order to introduce them into one or more cavity members 14 as shown in fig. 6. As can be clearly seen in fig. 6, the cavity member 14 generally comprises a base layer 26, a cover layer 28, and a honeycomb structure 30 disposed between the base layer 26 and the cover layer 28. The base layer 26 and the cover layer 28 are advantageously made of glass fibre mats impregnated in epoxy resin, wherein the honeycomb structure 30 is made of aramid fibres or paper impregnated in phenolic resin.
For introduction into the cavity member 14, the connecting element 10 is driven in rotation in the direction of the arrow 34 by means of a tool 32 at the tool placement location 22 and is loaded with an axial force acting along the longitudinal axis 18 in the direction of the cavity member 14, i.e. in the direction of the arrow 36. As can be clearly seen in fig. 5, the tool seat 22 of the connecting element 10 shown in fig. 1 to 5 comprises three eccentrically arranged blind holes 33.
When introducing the connecting element 10 known from the prior art shown in fig. 6, it has been shown that: their fastening in the cavity member 14 is insufficient to some extent, so that the connecting element 10 is partially detached again from the cavity member 14.
The connecting element 10 according to the invention shown in fig. 1 to 5 therefore has an expansion section 40 made of a heat-activatable expandable material on the circumferential surface 38 of the base part 16 extending between the upper side 20 and the lower side 24. For this purpose, a circumferential groove 42 is provided in the base part 16 in the region of the upper quarter facing the upper side 20, in which groove the expansion section 40 is arranged such that a surface 44 of the expansion section 40 is flush with the circumferential surface 38 of the base part 16 in the dispensing state.
The heat activatable expandable material is configured to expand under the action of heat. The heat-activatable material is a thermoplastic synthetic material comprising a heat-activatable blowing agent. Here, it is conceivable that: the blowing agent sublimes upon heating. The thermoplastic synthetic material of the base element 16 is polyamide (polyamide 6, polyamide 66 or polyamide 666) or polypropylene. Here, it is conceivable: the base part 16 consists entirely of thermoplastic synthetic material. However, it is also conceivable: the base part 16 consists of a thermoplastic synthetic material and a corresponding proportion of glass fibers.
When introduced into the cavity member 14, the heat-activatable expandable material of the expansion section 40 can expand into the cavities 12 of the honeycomb structure 30 of the cavity member 14 due to the heat generated by the friction between the connecting element 10 and the cavity member 14, so that an additional undercut is created below the cover layer 28 of the cavity member 14, by means of which the connecting element 10 can be securely fastened in the cavity member 14. Upon introduction into the cavity member 14, the coupling element 10 is applied by the tool 32 with an axial force in the range of about 800 newton to about 1200 newton, preferably about 1000 newton, and is driven at a rotational speed in the range of about 4000 rpm to about 6000 rpm, preferably about 5000 rpm.
The connecting element shown in fig. 1 to 5 has a length 46 (marked in fig. 6 for clarity) in the direction of the longitudinal axis 18, which is selected such that the connecting element 10 introduced into the cavity member 14 penetrates completely through the cavity member 14. Because partial melting of the connecting element 10 occurs when the connecting element 10 is introduced into the cavity member 14, the original length 46 of the connecting element 10 is about 30% greater than the thickness 48 of the cavity member 14.
For process-technical reasons, the connecting element shown in fig. 1 to 4 has a radius 50 in the range from 1 mm to 2 mm at the transition region between the underside 24 and the circumferential surface 38.
The connecting element 10 shown in fig. 1 has only one through-opening 52 in the base part 16, which opening is arranged concentrically to the longitudinal axis 18.
The connecting element shown in fig. 2 to 4 has a metal sleeve 54 which is arranged concentrically to the longitudinal axis 18 in the base part 16 and is at least partially encapsulated by the thermoplastic synthetic material of the base part 16. In the present case, the metal sleeve 54 is made of aluminum. However, it is also conceivable: the metal sleeve 54 is made of stainless steel.
To prevent twisting relative to the thermoplastic composite material of the base member 16, the metal sleeve 54 shown in fig. 2 has a square or hexagonal head 56. However, it is also conceivable: knurling, ribbing, and/or grooving may be provided on the surface 58 of the sleeve 54.
The metal sleeve 54 shown in fig. 3 and 4 has a surface 58 that is plasma treated by plasma nitriding. The adhesion of the thermoplastic composite material to the metal sleeve 54 can thereby be improved. The metal sleeve 54 of the connecting element shown in fig. 3 and 4 also has a cylindrical opening or bore 60, so that a cable can be passed through said opening or bore 60 when the connecting element 10 is introduced into the cavity member 14.
The base part 16 of the connecting element 10 shown in fig. 2 and 3 has an opening 62 which is arranged concentrically with the longitudinal axis 18 of the connecting element 10. In the connecting element 10 shown in fig. 4, the metal sleeve 54 is closed off by the base part 16 in the region of the underside 24. If the metal sleeve 54 is closed by the base part 16 in the region of the underside 24, the underside 24 of the base part 16 must be pierced by the tool 32 driving the connecting element 10 when being introduced into the cavity member 14, so that an opening extending through the connecting element 10 along the longitudinal axis 18 from the upper side 20 to the underside 24 is produced. Accordingly, the cable may then be passed through the cavity member 14 through the metal sleeve 54.
Overall, an inexpensive possibility for permanently fastening the connecting element 10 firmly in the cavity component 14 is provided.
